The technique stops the
2、AIDS virus from attacking its target-cells in the bodys defense system. When AIDS virus enters the blood, it searches for blood cells called T4 lymphocytes (淋巴细胞). The virus connects to the outside of T4 lymphocytes, then forces its way inside. There it directs the cells genetic (基因的) material to pr
3、oduce copies of the AIDS virus. This is how AIDS spreads.Researchers think they may be able to stop AIDS from spreading by preventing virus from connecting to T4 cells. When AIDS virus finds a T4 cell, it actually connects to a part of the cell called CD4 protein.Researchers want to fool the virus b
4、y putting copies or clones of the CD4 protein into the blood. This way the AIDS virus will connect to the cloned protein instead of the real ones. Scientists use the genetic engineering methods to make the clones. Normally a CD4 protein remains on the T4 cell at all times. The AIDS virus must go to
5、it.In a new technique, however, the cloned CD4 protein is not connected to a cell. It floats freely, so many more can be put into the blood to keep the AIDS virus away from real CD4 proteins on T4 cells. One report says the AIDS virus connects to the cloned proteins j ust as effectively as to real p
6、rotein. That report was based on tests with blood cells grown in labs. The technique is just now beginning t o be tested in animals. If successful, it may be tested in humans within a year.1. The new technique can _.A. cure AIDS B. kill the AIDS virusC. prevent the AIDS virus from spreading D. test.
7、5 Which of the following could be the best title of this passage?A. AIDS-a Fatal Disease. B. A New Technique in fighting AIDS.C. A Report on the Spread of AIDS Virus. D. The Technique of Cloned CD4 Protein.Passage TWOQuestions 6 to 10 are based on the following passage.During the early ears of last
8、century, wheat was seen as the very lifeblood of Western Canada. When the crops were good, the economy was good; when the crops failed, there was depression. People on city streets watched the yields and the price of wheat with almost as much feeling as if they wee growers. The marketing of wheat be
9、came an increasingly favorite topic of conversation.War set the stage for the most dramatic events in marketing the western crop. For years, farmers mistrusted speculative(投机的) grain selling as carried on through the Winnipeg Grain Exchange. Wheat prices were generally low in the autumn, but farmers
10、 could not wait for markets to improve. It had happened too often that they sold their wheat soon after harvest when farm debts were coming due(到期),only to see prices rising and speculators getting rich. On various occasions, producer groups asked for firmer controls, but governments had no wish to
11、become involved, at least not until wartime wheat prices threatened to run wild.Anxious to check(控制) inflation(通货膨胀) and rising living costs, the federal government appointed a board(董事会) of grain supervisors to handle deliveries from the crops of 1917 and 1918. Grain Exchange trading was suspended
12、(暂停) and farmers sold at prices fixed by the board. To handle the crop of 1919, the government appointed the first Canadian Wheat Board, with full authority to buy, sell, and set prices.6. The author uses the term “lifeblood”(Line1, para1.) to indicate that wheat was _.A. difficult to produce in lar
13、ge quantities B. was easily affected by animals and plantsC. essential to the health of the country D. expensive to gather and transport7. According to the passage, most farmers debts had to be paid _. A. when the autumn harvest had just been completed B. because wheat prices were high C. as soon as
14、 the Winnipeg Grain Exchange demanded payment D, when crop failure caused depression 8. According to the passage, wheat prices became uncontrolled because of conditions caused by _. A. farmers B. supervisors C. weather D. war9. The word “check” (Line 1, Para.3) could best be replaced by which of the
15、 following?A. control B. investigate C. finance D. reinforce10. According to the passage, a preliminary step in the creation of the Canadian Wheat Board was the appointment of _.A. the Winnipeg Grain Exchange B. a board of supervisorsC. several producer groups D. a new governmentPassage ThreeQuestio
16、ns 10 to 15 are based on the following passage.Yellowstone Park is visited by two million people every summer and is the oldest, largest and most visited wilderness in the world. All are welcome and are invited on arrival to leave their cars and explore on foot. Yellowstone, a national park for ever
17、 100 years, lies in the State of Wyoming, to the east of the Rocky Mountain. It is also in the center of the North American continent, midway between the equator and the North Pole, at a height of over 2300 meters. The very cold winter in this area closes the park around mid-November and lasts until
18、 April or even May. In February thetemperature falls as low as 60F degree below freezing, and the animals that spend winter in the park are best able to live in the conditions such as bison, wapiti, beavers and otters. Fortunately, the area around the hot springs and geysers becomes a centrally heat
19、ed oasis(绿洲) in the desert of snow, providing warmth and a certain mount of food for the animals. Bison used to go around the plains in their millions until they were hunted almost to extinction(灭绝) by white men with guns. In 1900 only two dozen of them remained in the park. However, since they beco
20、me a protected animal, their numbers have risen to over two thousand. The end of winter is the most dangerous time for the animals as food becomes even less and they take great risks(冒险) to find it, such as walking across thin ice. This period is known as “winterkill”, when many of the weak and the
21、old die, often from being too tired out, thus providing food for scavengers such as the coyote (a kind of wolf). With the arrival of summer, plants reappear and the animals fill themselves with rich food. The young grow strong and the tourists return to enjoy the warmth or 4 months before Yellowston
22、e Park freezes over again.11 Bison used to go in danger.

25、on the following passage.What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist(乐观者), a leader, an active person who enjoy life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If
26、you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologist(心理学家) tell us and they should know, because they have been seriously studying the meaning of color preference, and the effect that colors have
27、 on human beings. They tell us that we dont choose our favourite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly. A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red
28、 dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(压抑). Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder and have fewer accidents when their machines are painted orange rather tha
29、n black or dark gray. Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And dont forget that anyone
30、can guess a lot about your character when you choose a piece of handkerchief or a lampshade. 16.
